Patent number: 11473710Abstract: A heated drain or vent pipe system provides a low-cost and efficient temperature regulator for drain or vent pipes that are exposed to freezing temperatures to prevent the pipes from freezing. The heated pipe system includes an embedded resistance wire connected to a transformer that supplies a low voltage of electricity to the resistance wire. The resistance wire heats up due to electricity passing through the wire and transfers that heat to the pipe. The resistance wire is embedded in the wall of the pipe and maintains the pipe at a temperature above freezing. The heated pipe system may include a safety limit switch to disable the flow of electricity to the resistance wires if the pipe is overheating. The heated pipe system can be installed with air conditioning system drains, roof drains, and two-way vents that are exposed to freezing temperatures.Type: GrantFiled: July 6, 2020Date of Patent: October 18, 2022Inventors: Chad Michael Arntz, Michael C.
